mRNA expression of tumor-associated genes (measured by qPCR) in AT1 prostate and Walker-256 mammary carcinoma tumors in vivo 24 h after (a) inducing metabolic acidosis by forcing glycolytic metabolism or (b) intratumoral injection of lactic acid. n = 4–22; (*) p < 0.05, (**) p < 0.01 vs. control; (^#) p < 0.05, (^##) p < 0.01 AT1 vs. Walker-256 tumors
